`Application filed-May 10, 1922. Serial No. 559,885.

To all LU/wm t may concer/a. i

Be it known that I, JNs MHLow, a citizen of Sweden, and residing at Malmo, in the Kingdom of Sweden, have invented 'certain new and useful Improvements in Bases for Posts, Flagstaffs, and the like,`of which the following is a specification.

' This invention relates kto a base for posts, flag-staffs and the like and has for its object to retard the dilapidation of the lower end of the same as a result of the varying atv inospheric conditions to which the posts `are subjected. With this object in View' the lower part of the post mounted in a sleeve shaped base and above the ground is arranged in such a manner that it is continually subjected to an effective ventilation. The base is substantially made of reinforced concrete but may also consist of other material, for instance cast iron.

The invention is more particularly described with reference to the accompanying drawings, in which:`

Fig. l is a sectional view of a base showing two different forms one on each side of the vertical central line'. Fig. 2 shows in a similar manner a third modification of the upper part of a base. Fig. 3 is a horizontal section after the line A-B in Fig. 1 and Fig. 4 is a section after the line CMD in the saine figure. Fig. 5 is a horizontal section after the line E-F in Fig. 2 and Fig. 6 shows a detail of Fig. 5 on a larger scale. Fig. 7 shows a detail of Fig. l and Fig. 8 is a side view of the reinforcement in the sleeve shaped base. Figs. 9-11 are details of Fig. 8. j y

Referring to Fig. 1 5, 1 is the .sleeve shaped base and 2` the lower part of the post ned therein. The ground is indicated by 3.

As shown by Figs. 1 and 2 the post is ar'- ranged completely above the ground with its lower tapered part fitting in a correspondingly tapered aperture of the base, the post resting with its chamfered end upon proje'ctions 4C integral with the base. According to Fig. 2 these projections may be dispensed with on account of the tapered forms ofthebase and the post. As illustrated by the drawings thebase and post show a conical tapering, but itis obvious vthat also a prismatic form of these parts may serve the saine purpose, for instancewhen using tubular masts.

Referring to the left side part of Fig. l the surface of the lower part of the post smooth whilst the part of the base sur-iii rounding the post is provided onthe inside with ridges or lists 5 arranged lengthwise or somewhat slantwise thereat and forming the direct resting surfaces for the post...L Grooves or channels 6 (Figs. 3 and 7) are formed between the lists 5 which in the direction of the arrows shown in Figs. -1 and 2 allow free air circulation along the whole length of that pai't'of the post which is inl..

the base and in order to obtain an effective change of airports 7 are arranged in the base underneath the end of the post but above the ground. These ports may be covered withy a network to prevent strange matter or small animals, (rats and the like) to get into the interior of the base, the lower end of which `fixed in the ground preferably is open and not fitted with a bottom, so that water running down along the post through the channels 6 and the lower part of the base may be absorbed by the earth and the lower part of the base may form a catclrbasinif the absorption should not come to pass withsuiiicient speediness. Under no circumstances `can water thus accumulated reach the post because it will beforehand through the holes 7. y

The'modification shown onthe right hand run away .side of Fig. 1 differs from the above by the L The lists 9 may if so desired be cut away in the middle of the part of the post placed in the base for facilitating the airv circulation so that an annular channel l0 is formed around the post thereat (Figs. 1 and 4C) and according to the left side of Fig. l the saine channel may be formed by omittingV corresponding parts of the ridges 5. y

lith the same object in view according to Fig. 5 one or several liners maybe used between the post and the base, which in this case have smooth surfaceswhilst the liners consist of two rings, preferably of iron, of such a size that they fit in the base near the upper edge and somewhat above the air inlet Corrugatd iron bands 12 are fixed to the inside of the rings 11, and thelower part of the. post can rest upon the free ridges of the corrugated band as will be seen from the illustration. The number of such rings 11, 12 may vary and be chosen to` suitcircunf-` stances, and even one ring 11, 12 only may be sufficient if it is enlarged in width to such an extent that it becomes substantially7 equally broad as the length of the part of the post being in the base.

It should be obvious that the two modifications as shown in Fig. 1 could be combined one with the other so that channels and lists appear Vas well on the base as on the post7 and as regards the modification of Fig. 3 the corrugated rings could be fixed to the base or the post, and the invention also includes such modifications.

The base is preferablymade of concrete and for diminishing the size of same reinforced concrete is employed. A preferred form of the reinforcement is shown in the drawing, special reference being had to i ,Figs 841, in which the reinforcement preferably consists of a.Y number .of oblong rectangular hoops 13 imbedded lengthwise in the base, an iron wire 11i being wound around the hoops and fixed thereto' thus forming aY substantially Vcylindric wire basket (Fig. 8). Rings 15 are arranged at the upper and lower end of this basket, the hoops 18 being bent over saidrings 15 as shown in Fig. 11. The Vvarious parts of the reinforcementare preferably welded together and the windings of the wire 11i are wound closer together as vshown by 14 at the ends of the basket and also at that part which will be Vjust v'above the ground 3, as the base at this place partly issubjected to the greatest strain and partly weakened bythe air inlets 7, and furthermore reinforcing wire hoops 16 may be arranged at and around the inlets 7 (seeFigs. 840).

Posts subjected to a greater strain in one direction than 'in another may be provided with .stay-rods 17 (Fig. 1) fixed to the lower end of the baseiand spaced in a usual mannerV by distance-pieces 1S, of which the lowermostrests upon the base and is fixed by means of a rod 19 slanting downwards towards the lower end of the base, said rod .being pivoted to a ring which is fastened to the base and provided with one or several claws 21 gripping around the. lower edge of thegbase.

In orderlto distribute the pressure of the base upon the Vearth over a larger surface special`V- pressure plates 22 may be employed Y which ,are fixed tothe outer vside of the 'base the base in order that they may be set for taking up pressure in a desired direction. If the post is provided with a stay-rod the lowermost pressure plate may be arranged witha slot 24 for the rod 19 to pass through.
